How hot can aluminum heads get before they warp?

FYI-When we ran the engine with the pump attached in place of the cap the engine was nice and cool, under 210 degrees. No change in pressure was seen and even after we shut her down it was a few minutes before the pressure dropped enough to remove the tester. Also, I forgot to ask you if I need to drill a hole for pressure a la OEM thermo. in the Shaw 180 thermo.

I am really beginning to think that my problem has a lot to do with my car being parked on a decline. Every test we've done has been when the car was on a decline, so hopefully 1) moving the car out of the driveway 2) emptying and re-filling the coolant system with water (to rid the system of air pockets), 3)putting in a good 180 thermo., and 4)installing the Flex-fan (w/out clutch but with shroud) should keep me cool. But once again the shroud probably won't come in until Thurs. so I won't even attemp to turn her over tonight. I'll just install the thermo. and fan and get prepared for the shroud and the final test Thurs. Boy am I gonna be nervous! This car has been stressing me as I've spent almost a year researching and building this car. Thanks a lot for the help. I really appreciate it. You sound like a pro and I'm lucky to have you helping me along with all the other fellow "Stangers" and Ford Men.
